The Cyclospora Files
What's actually safe to eat. A source-checked summary of what the CDC, FDA and state health departments actually say — as opposed to what the internet, in full panic, is screaming at you.

Breaking · The Source Was Found
They caught it: shredded iceberg lettuce at Taco Bell
On July 16–17, CDC and FDA named a source for the outbreak: shredded iceberg lettuce from a single supplier in central Mexico — Taylor Farms de México — served at Taco Bell locations in five states.
This is a real change from a week ago, when nothing had been identified. FDA's traceback converged on that one supplier, and about 90% of the sick people interviewed reported eating iceberg lettuce. Taco Bell has committed to stop using lettuce from that supplier, and Taylor Farms de México is voluntarily pulling all of its central-Mexico iceberg lettuce from the US market.
What this means for you
CDC's specific advice: do not eat shredded iceberg lettuce served at Taco Bell locations in Indiana, Kentucky, Michigan, Ohio and West Virginia. CDC explicitly says shredded iceberg lettuce sold in grocery stores, or served at other restaurants, is not affected. You do not need to swear off lettuce.
The July 20 twist — and why the recall still stands
A Taylor Farms lettuce sample that had tested positive for Cyclospora was later determined by FDA to be a false positive. The recall and the advisory still stand — the link was built from the traceback and the patient interviews, not from that one lab test. A single sample flipping does not un-identify the source.
The 30-Second Version
Deep breath. Here's the whole story.
There is a real, unusually large outbreak of a parasite called Cyclospora. It causes prolonged watery diarrhea. It is treatable with antibiotics and no deaths have been reported.
As of mid-July, the main source has been identified — shredded iceberg lettuce served at Taco Bell in five midwestern states (see above). That's a big deal: for weeks nothing was named. Not every 2026 Cyclospora illness is necessarily tied to this one vehicle, but CDC now links essentially all of its confirmed domestic cases to it.
You do not need to stop eating produce. Cooking kills this parasite — Michigan health officials put the threshold at 158 °F / 70 °C. Washing helps but is not a guarantee. If you're immunocompromised, elderly, or caring for a young child, lean toward cooked and peeled produce for now.
The Body Count
The numbers
1,645US cases confirmed by CDC
141Hospitalized
0Deaths
34States reporting
CDC Health Alert Network figures, current as of July 14, 2026. Lab-confirmed, domestically acquired cases since May 1, 2026. For comparison, only 249 cases were reported nationally over the same May–July window in 2025.
The 1,645 is just the confirmed core
CDC also says it is aware of more than 5,100 additional cases that still require further analysis to confirm as domestically acquired cyclosporiasis — which is why you'll see headlines citing "up to 7,000" total. State counts run higher still: Michigan alone has reported more than 3,300 cases (state count, mid-July) and the true number is certainly higher, because mild cases often go untested. State health departments have fresher numbers than CDC does.
The Hot Zone
Where it's hitting — outbreak heat map
The identified outbreak — the Taco Bell shredded-iceberg-lettuce one — is concentrated in five midwestern states, with Michigan as the clear epicenter. CDC counts this cluster at 1,644 illnesses and 94 hospitalizations across these five states — essentially all of its confirmed domestic cases.

Safe Harbor
What's safe
Lowest risk — heat and packaging do the work
✓Anything cooked to 158 °F / 70 °C or hotterMichigan health officials: this temperature kills Cyclospora. Soups, stews, stir-fries, roasted vegetables, casseroles.
✓Meat, poultry, fish, eggs, rice, pasta, bread, grainsNot implicated. Cyclospora outbreaks are linked to fresh produce and contaminated water.
✓Canned and shelf-stable fruits and vegetablesHeat-processed.
✓Pasteurized juice, milk and dairyNot implicated.
✓Fruit you peel yourselfBananas, oranges, avocados. Wash the outside first, then peel.
✓Iceberg lettuce from the grocery storeCDC says grocery-store shredded iceberg, and iceberg at other restaurants, is not part of this outbreak — only the Taco Bell supplier's lettuce in the five affected states.
Fine with normal care — most fresh produce
CDC has not told anyone to stop eating fresh produce. Standard CDC and MDHHS food-safety advice still applies:
Wash your hands with soap before and after handling produce. (CDC)
Wash all fruits and vegetables thoroughly under running water before eating, cutting or cooking. (CDC)
Scrub firm produce (melons, cucumbers) with a clean produce brush. (CDC)
Cut away bruised or damaged spots. (CDC)
Refrigerate cut, peeled or cooked produce within two hours. (CDC)
Wash and sanitize the utensils, cutting boards and surfaces you use for produce. (MDHHS)
Handle With Gloves
Where I'd be a bit more careful
The clearest precaution is the specific one: if you ate at a Taco Bell in Indiana, Kentucky, Michigan, Ohio or West Virginia and you're sick, mention Cyclospora to your doctor. Beyond that, Michigan — the hardest-hit state — has a broader precaution list. Two things to understand before you read it:
Read this first
These foods are on Michigan's list because of past Cyclospora outbreaks — foods previously linked to Cyclospora in the US and Canada. The vehicle in this outbreak is the Taco Bell iceberg lettuce; the rest of the list is general precaution, not evidence about the current cases.
!Bagged salad mixes & leafy greensMichigan: buy whole heads instead, discard the outer 2–3 layers, wash the inner leaves. Cook them if you can.
!RaspberriesThe bumpy surface is genuinely hard to clean — the parasite hides in the crevices. Cooked (pies, jam) is safest.
!Fresh cilantro & basilSeparate the leaves, rinse thoroughly under running water. Cooking is safer.
!Green onionsTrim the root end, remove the outer layer, rinse thoroughly. Cooking is safer.
!Snow peasRinse while rubbing the surface. Cooking is safer.
Heads up: the agencies disagree on prewashed
CDC's standing guidance says produce labeled "prewashed" does not need to be washed again at home. Michigan is telling people to skip prewashed bagged mixes entirely. Michigan is being more conservative because it's in the middle of an outbreak. Neither is wrong — pick based on where you live and how cautious you want to be.
The Vulnerable
If you're higher-risk
Michigan singles out people on chemotherapy, organ transplant recipients, anyone immunocompromised, infants and young children, and elderly people. The illness itself is rarely life-threatening — the danger is dehydration from repeated diarrhea. CDC notes that people who are immunocompromised or in poor health may be at higher risk of severe or prolonged illness.
For this group during the investigation: favor cooked produce, peelable fruit, canned produce, and food prepared at home over raw salads and restaurant produce. It's a low-cost precaution.
Myth Autopsy
Things people are getting wrong
"Nobody knows what's causing it — anyone naming a food is guessing."
That was true a week ago. It isn't now. As of July 16–17, CDC and FDA have named the source of the outbreak: shredded iceberg lettuce from Taylor Farms de México, served at Taco Bell in five states. The traceback and the patient interviews got there. (If someone is naming a grocery brand or your local supermarket, though — that's still a guess. Only the Taco Bell supplier lettuce is implicated.)
"So all iceberg lettuce everywhere is contaminated now."
No. CDC is specific: only shredded iceberg lettuce served at Taco Bell locations in IN, KY, MI, OH and WV. Iceberg you buy at the grocery store, or eat at another restaurant, is not part of this outbreak.
"Just wash it really well and you're fine."
Washing reduces risk and is worth doing — but no agency says it removes Cyclospora reliably, and the official advice for the riskiest items always ends with "cooking is the safest option." FDA, in its guidance for growers, says chlorine and other common antimicrobial chemical treatments are not effective against this parasite. Cooking (158 °F / 70 °C, per Michigan MDHHS) is the only step officials describe as actually killing it.
"A vinegar / baking soda / produce-wash soak will kill it."
There is no evidence for this. Health officials recommend plain running water and a produce brush. Sanitizers are recommended only for surfaces and utensils, never for the food itself.
"Freezing kills it, so frozen berries are safe."
Michigan's exact words: freezing "may reduce but does not guarantee elimination of the parasite." Frozen is a reasonable alternative to fresh raspberries — it is not a guarantee.
"It's imported produce, so buy local / American and you're safe."
This outbreak's lettuce did come from Mexico — but that's not a reliable rule. Cyclospora comes from human fecal contamination of food or water, and FDA has found it on domestically grown produce too (confirmed in US-grown cilantro in 2019). "Local" and "American" labels don't tell you whether a given item is safe.
"Stay away from anyone who's sick with it."
Direct person-to-person spread is unlikely. After leaving the body, the parasite needs at least 1–2 weeks in the environment before it can infect anyone. (Keep washing your hands anyway — norovirus and everything else absolutely do spread that way.)
"Don't drink the tap water."
There is no national advisory against tap water, meat, dairy, or grocery produce broadly. The named vehicle is one supplier's restaurant lettuce. Don't let anyone stretch that into a blanket panic.
Know The Signs
Symptoms & when to call a doctor
Symptoms typically start about a week after exposure, though the range is 2 days to 2 weeks or more. They can include:
Watery diarrhea — frequent, sometimes explosive — that persists
Loss of appetite and weight loss
Cramping, bloating, gas, nausea
Fatigue, body aches, low-grade fever
Symptoms that improve and then come back — a hallmark of this one
Call a clinician if
Diarrhea lasts more than a few days, is severe, contains blood, or you're getting dehydrated (dizziness, very dark urine, not urinating, confusion). Dehydration is the real risk here.
Say the word "Cyclospora"
It's treatable — the standard treatment is the antibiotic TMP-SMX (Bactrim). But identifying Cyclospora requires a special lab test that is not part of routine stool testing, so tell your clinician specifically that you're concerned about it — and mention if you ate at a Taco Bell in the five affected states. You may need to give samples on more than one day. Untreated, the illness can last anywhere from a few days to a month or longer.
Different Monster
One unrelated thing worth knowing
There is a separate recall that is not Cyclospora: an E. coli O145:H28 outbreak linked to frozen GreenWise-brand organic blueberries sold at Publix.
Product: 10-oz packages, lot code 60401, best-by Feb 9, 2028
Sold in: AL, FL, GA, KY, NC, SC, TN, VA
Outbreak: 12 illnesses, 4 hospitalizations, no deaths
What to do: check your freezer; throw it out or return it
Different bug, different food, different investigation. Don't let the two get merged into one panic.
